Title: Imbalanced braking device
IPC: B65G13/00
Filed: 1971-11-18
Abstract: 1313984 Roller conveyers N J FROIO 18 Nov 1971 [23 Nov 1970] 53654/71 Heading B8A [Also in Division F2]  A braking device for retarding moving objects (such as pallets on a gravity conveyer) comprises a housing or retainer, a gear train supported by the housing and including at least a first gear and a terminal gear, intermeshed so as to progressively increase the angular velocity as the first gear in the train is rotated, at least the last gear in the train being imbalanced about its rotational axis, and means for translating the movement of the moving objects into rotational movement of the first gear so that rotation of the gear train acts to retard the movement of the objects. As shown, a gear retainer is made up of two half sections each consisting of a circular plate 35, Figs. 2 and 3, a circular hub 44 with a squaresection outer bore 48 and a circular section inner bore 46, pins 36 on spacers 38, and complementary fitting apertures 40. The gear train consists of a first gear 54 whose teeth extend above plates 35, intermediate gears 56, 58, 60, intermeshed to be driven at successively higher speeds, and a last gear 62 having asymmetrical holes 64 to produce imbalance. Such holes may be filled with lead or the like. Retatably mounted on the hubs 44 are half sections 24, connected together, of a cylindrical housing, one section having internal planetary gear teeth 26, Fig. 2, meshing with the first gear. A rubber or like non-skid band 32, under slight tension, occupies a peripheral indentation 30 of the housing. Such an assembly, with the hubs 44 mounted non-rotatably, may form part of a gravity roller conveyer 13, Fig. 1, so that an article 22, rotating the housing by contact indirectly drives the gear train and is thereby braked. As the speed increases, the imbalance produces sharplyincreased braking forces, due in part to increased tooth friction and bearing friction. Some energy may also be dissipated in vibratory motion. For ease of manufacture, all the gears (including the last gear before unbalancing treatment) may initially be of two types only. Also, the two half sections 24 may be identical, in which case the internal teeth 26 on the right of Fig. 3, are superfluous. All components may be moulded from nylon polyamide resins with, optionally, glass fibres for reinforcement and molybdenum disulphide for self-lubrication. An assembly such as that shown in Fig. 3 but with band 32 omitted and one of the edges forming recess 30 removed may be fitted into each end of a comparatively long "gravity" roller (Fig. 6, not shown). In a modification (Fig. 7, not shown), the first gear is common to two gear trains, the last gear of each being imbalanced. In Fig. 8 (shown with parts of an outer housing removed), a resilient roller or wheel 98 is contacted by a moving article whereby imbalanced gear 106, 108 is indirectly driven. One or more intermediate gears may be imbalanced also.

In a heating system, particularly a hot water system for a building operating on the recirculating principle, wherein the water is heated in a cylindrical shell containing heating coils 17 through which steam is passed, the temperature of a sample flow of the recirculated water to which make-up water has been added is sensed by a temperature responsive device 29 which is adapted to regulate the amount of steam fed to the coils 17. Make-up water is added via pipe 35 to replace any-hot water used up in the building. The majority of the recycled water plus makeup water enters the heat-exchanger to be reheated through air inlet 23 equipped with a diffuser 24, but a small proportion (representing the sample flow) is admitted through an inlet 26 connected to a perforated chamber 27 containing the temperature responsive device 29. The device 29 controls a valve 45 in the steam line 44 feeding the coils 17. Valves 41, 42 are provided to vary the proportions of recycled and make-up water entering the top of the heat exchanger through the inlet 26. Reheated water leaves through an outlet 25. Each heating coil 17 comprises a series of spiral coil members 18 interconnecting an inlet header 19 and an outlet header 20 both of which protrude through the shell and terminate in pipe connections 21, 22.

Abstract: 1412016 Automatic control of welders MATSUSHITA ELECTRIC INDUSTRIAL CO Ltd 29 Nov 1972 [30 Nov 1971 (2)] 55040/72 Heading G3R The output of an electric welder is controlled by an operational amplifier having input signals S 1 , S 2  and So corresponding respectively to a desired welder output, actual welder output and a signal that produces the desired welder output in the absence of any other signals to the amplifier. The operational amplifier calculates a signal S 1  where S = aS 0  + b(S 1 -S 2 ), that is used to control the welder output. As shown, the signal S 2 , dependent upon the welder current, is fed back to the adder-subtractor circuit 13 (including one or more operational amplifiers 14) via a smoothing circuit 19, for example a low pass filter. The output S of circuit 13 passes through a time delay 18 (e.g. a servomotor with a long time constant) to welder control means 15 which could be a variable impedance or saturable reactor. Under stable running conditions the welder output S 2  is maintained at the desired value S 1  by the signal So. Upon starting or under non-welding conditions with S 2  = 0, the welder output is maintained at approximately the desired level by signal S o  until the feedback signal S 2  is produced and stable running conditions are assumed. Smoothing circuit 19 and time delay 18 can be omitted, and signals S 1  and So obtained from a common source rather than, as shown, from separate signal generators 11, 12.

Title: Indicating or detecting apparatus for nuclear radiation such as gamma rays
Inventor: LOVEDAY GEORGE CHRISTOPHER
IPC: G01T1/164
Filed: 1967-12-07
Abstract: 1,213,478. Scintillation detectors. EKCO ELECTRONICS Ltd. Nov. 21, 1968 [Dec. 7, 1967], No.55591/67. Heading G1A. Nuclear radiation such as X-rays is detected by a scintillation detector arrangement comprising an array of scintillator elements, arranged in a coordinate matrix, which are viewed by an array of photo-multipliers having overlapping fields of view. The number of photo-multipliers is lower than that of the scintillator elements as shown in the simple arrangement of Fig. 4 where four detectors cover an array of sixteen elements. In a practical apparatus the numbers could be, for example, 70 and 1500, respectively. In Fig. 4, the outputs of the detectors of each row (X and Y directions) are summed, giving outputs on lines 40, 42, 44, 46. These lines feed charge sensitive amplifiers 50- 56, pulse height analysers 58-64 and two common systems of AND-gates 66-72 and 80-86, which are followed by OR-gates 74, 76 and 88, 90. Output lines Y 1  - Y 4  and X 1  - X 4  are provided by this circuit, pulses on any one from each set of which indicate the scintillator element in which a scintillation is occurring. The arrangement operates on the principle that elements directly beneath the centre of a photo-multiplier produce a pulse of height say 1 volt, and others progressively further away produce pulses of 0À7, 0À5 and 0À3 respectively. The use of the pulse height analysers and gating arrangements provides that the outputs represent the coordinate position of detected radiation events. The outputs Y 1  - Y 4  and X 1  - X 4  may be stored in a magnetic core or tape or applied to deflection control and bright-up circuits for a cathode ray tube, Fig. 5 (not shown), which provides an analog display of the radiation detected by the system of Fig. 4. In a more extensive system having a 2 x 3 detector array and 4 x 7 scintillator element array, Fig. 6 (not shown), circuitry is described for ensuring that only pulses due to X-rays of a predetermined selected energy level are produced on the Y and X output lines.
